Question

A garden is in the shape of a semicircle with a radius of 25 feet. Fencing is placed around this garden. How much fencing, in feet, is needed to go around this garden? Give me the most accurate answer and SHOW ALL YOUR WORK.

Answer 1

Answer: the fencing need to be 125 feet

Answer 2

Solution:
Radius(r)=25 ft
Perimeter(P)=?

We have,
Perimeter of a semi-circle(P)= πr+2r
=(22/7)*25+2*25[Since, π is approxiamately equals to 22/7]
=22*25/7 +50
=600/7
=85.714 ft

Since the fencing is done around the semi-circular garden, the length of fencing=perimeter of the garden.

Therefore, 85.714 ft of fencing is required to go around the garden.

Pls give thanks!
Thank you!
